Hello everyone, I'm working on fluid dynamical model with considering Laminar flow and Heat transfer in fluid model physics. While setting the initial velocity = 0 [m/s] and initial pressure = 0 [atm] in Laminar flow model and considered Spherical heat source (with power 57 mW) in the Heat transfer in fluid. When I run the program, the temperature profile result generated but velocity profile shows null result as shown in below figure. But when I choose the initial pressure = 1 [atm] with initial velocity = 0 [m/s]. It generates the velocity profile of fluid flow shows results but velocity in the range of 10e-20 [m/s] which is too small. So anyone have proper reason for this please explain.
